Description

FIELD OF THE INVENTION [0001] The present invention relates to a water film forming fire-

The present invention relates to a water-film-forming fire-resistant door frame and a construction method thereof, and more particularly, to a water-building fire-proof door frame and a method of manufacturing the same, This is about a water-film-forming fire-resistant door frame that can save lives, such as persons with disabilities and old people, by installing an air supply device and a water spraying device to prevent flames and toxic gas from being introduced into the city.

Recently, apartment buildings and residential complexes are being built in high-rise trends.

However, when a fire occurs in a high - rise apartment and a high - rise building, there is a problem that the elevated ladder of a fire truck can not be accessed to extinguish the fire.

In order to prevent such problems, recently, high-rise buildings are required to set separate fire escape zones.

However, these regulations do not apply to high-rise apartments and buildings built before such regulations are enacted, which is problematic because shelters are not fixed even though they are high-rise buildings.

In addition, according to the regulations, even if the building is installed with a shelter, most of the building materials in the room are made of flammable material and easily burned in the flame, so that it is surrounded by the flames. Therefore, there is a difficulty even to escape from the room and move to the shelter.

In order to solve such a problem, Korean Registered Patent Application No. 20-0331768 discloses a fire door made of wood for inserting a fireproof sheet between plywoods.

Fire doors are effective in terms of fire resistance to flames, but they still remain vulnerable to toxicity due to toxic gases.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[First Embodiment]

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a cross-sectional view of a water film forming fire door frame according to the present invention; FIG.

The water-film-forming fireproof door frame 10 of the present invention may be formed of wood or a synthetic resin material. The first embodiment may include the first end cover portion 100, the door receiving portion 200, the door supporting portion 300, And the second end cover portion 400 are integrally formed.

The first end cover portion 100 is formed of a side cover portion 110 covering the side end portion of the crown frame 1000 and a top cover portion 120 covering the top surface of the crown frame 1000, As shown in FIG.

The door cover 200 is formed at an inner side of the top cover 120 so as to protrude upward.

The door receiving portion 200 serves to support and accommodate the side end portion and the upper end portion of the door D, respectively.

The door supporting portion 300 is formed on the side of the door receiving portion 200 so as to be stepped upward.

A first water tank receiving part 310 is formed in the inside of the door supporting part 300 so that the upper part is opened.

A first through hole 320 for receiving the first nozzle unit 710 is formed on the lower side of the first water tank receiving unit 310.

A groove 330 for inserting the gasket 500 is formed on the stepped side of the door supporting portion 300 adjacent to the door receiving portion 200.

A side cover portion 410 covering the side end portion of the door frame 1000 and a top cover portion 300 covering the top surface of the door frame 1000 420).

2 is a view showing a first water tank in a water film forming fire-resistant door frame of the present invention.

The first water tank 700 is made of a metal material having corrosion resistance, such as stainless steel, and is formed to have a corresponding shape so as to be received in the first water tank receiving portion 310.

The first water tank 700 has a first nozzle part 710 formed at an lower end thereof so as to be inclined toward the door.

The first water tank 700 is installed in the first water tank receiving portion 310 and the first nozzle portion 710 of the first water tank 700 is connected to the first through hole 320, wherein the first nozzle portion 710 is installed in a direction toward the door.

2, a water channel 600 is connected to a side or an upper portion of the first water tank 700, and a valve 610 is installed in the water channel 600.

The valve 610 is configured to be manually operated or to be automatically operated through a fire monitoring sensor (not shown) in the building.

It is preferable that the water film-forming fireproof door frame of the present invention is installed at a door of a toilet, because it is more advantageous to secure a water channel than other interior spaces.

Also, since the toilet has a ventilation facility, it is relatively easy to discharge toxic gas, and water exists, which is advantageous in preparation for fire.

Next, the operation of the water film forming fire door frame will be described. 3 is a view showing an operational state of the water film forming fire door frame according to the present invention.

When a fire occurs, the valve 610 is automatically opened by a manual operation or a fire detection sensor (not shown) installed in the building.

When the valve 610 is opened, the water flows into the first water tank 700 through the water channel and the water is sprayed toward the door through the plurality of first nozzle units 700.

Water sprayed from the first nozzle unit 710 is sprayed onto the surface of the door so that the water film is formed over the entire door while flowing along the door.

Thus, the water film formed on the door prevents the door from being burned.

The water sprayed on the door flows along the door and penetrates into the gap between the door and the water-film-forming door frame 10 to form airtightness, thereby preventing the toxic gas from flowing into the inside.

In addition, the gasket 500 is formed in the water-film-forming fire door frame 10 of the present invention. In this case, the gasket 500 functions to buffer the shock of the door. In case of fire, To prevent double penetration through the gap.
